[Feature Request] Allow line wrap by default when rendering buttons vertically

What is the problem you are attempting to solve with this feature?

In Webchat, where action buttons are stacked upon each other, button text doesn't wrap which leads to ellipsis, making it unclear what a button might do, and providing a less than optimal user experience overall:

A description of your proposed solution to the problem

It should be possible for a host application to configure Webchat so button text is wrapped.

What alternatives or workarounds have you considered

A workaround is available via CSS.

Proposed solution

Add a new parameter in HostConfig to allow the host application to request that button text be wrapped. This should only apply to buttons when they are stacked on top of each other, not when they are lined up on a single row. By default, button text would continue to be truncated to maintain backwards compatibility. The new behavior would be opt-in.

QUESTION: Could we simply modify the default behavior and always wrap?

Start by reading the Webchat button-rendering behavior and the HostConfig entry point mentioned in the request. Determine how an opt-in setting can affect only vertically stacked buttons while preserving truncation for single-row buttons and the default behavior; done means the configured wrapping works without changing existing defaults.
